Solar panals

Right! That small switch is in Volts, I didn't notice. He should check the current and voltage on the same meter in absence of loads. Pull out all the fuses. Measuring the output with multimeter near the battery would be my preference though. Also, measuring the battery voltage at rest.

The photo of the Power Guard is displaying volts and reads about 11.6 volts which is low. Change the toggle switch so that it displays amps and see if you are getting any charge current.

I would guess that the toggle interrupts current from the roof mounted panel and the auxiliary input from the exterior mounted module. This may have been installed so that the combination of both modules does not overcome the capacity of the solar controller.
As was posted, you will need to measure the voltage at the output wires of the solar controller to see if power is being delivered to the batteries. For this (and other sundry electrical items), you will need an inexpensive meter and learn how to use it.

Photo bucket does not work with the image command apparently.

OK. There is a nice current out of controller, and some unknown voltage. Maybe everything works as it should. Measure the voltage on the cables at the very end, where they come to the battery - but not on the battery, disconnect them for measuring.

In future, when you post a link to image, use the "image" button in the editing window and copy-paste the link. Then it will show as image.
